چکیده
The title compound, [Ru(C(10)H(15))(NO)(HOCH(2)CH(2)OH)](CF(3)SO(3))(2), possesses a three-legged piano-stool geometry around the Ru atom, with an average Ru-O distance of 2.120 (6) Å and an Ru-N-O angle of 159.45 (14)°. The ethyl-eneglycol ligand forms a non-planar metallacyclic ring by chelating the Ru atom via the O atoms. The O⋯O distances of 2.554 (2) and 2.568 (2) Å are indicative of hydrogen bonding between coordinated ethyl-eneglycol and outer-sphere trifluoro-methane-sulfonate fragments. The crystal packing is stabilized by ionic forces and several CH(3)⋯·F (2.585 and 2.640 Å) and CH(3)⋯O inter-actions (2.391, 2.678, 2.694 and 2.699 Å) between the penta-methyl-cyclo-penta-dienyl ligand and trifluoro-methane-sulfonate anion. There is noticeable short inter-molecular contact [2.9039 (16) Å], between an O atom of the SO(3) group and a C atom of the penta-methyl-cyclo-penta-dienyl ligand.

In the title compound, [Zr(C10H15)2(C14H12NO)(CN)], the Zr(IV) atom is coordinated by two penta-methyl-cyclo-penta-dienyl ligands, the amidate ligand via the N and O atoms, and an additional C N ligand. The four-membered metallacycle is nearly planar (r.m.s. deviation = 0.008 Å). In the crystal, the mol-ecules are connected into centrosymmetric dimers via pairs of N-H⋯N hydrogen bonds.

The dinuclear title complex, [Ti(2)(C(10)H(15))(2)(C(7)H(2)F(5)O)(4)O], features two Ti(IV) atoms bridged by an O atom. Each Ti atom is bonded to a η(5)-penta-methyl-cyclo-penta-dienyl ring, two (penta-fluoro-phen-yl)methano-late anions and to the bridging O atom. The environment around each Ti atom can be considered as a distorted tetra-hedron.

The title compound, [Ru(C(10)H(15))(C(10)H(12)O)][B(C(6)H(5))(4)], crystallizes as discrete (η(5)-penta-methyl-cyclo-penta-dien-yl)Ru(η(6)-4-phenyl-butan-2-one)](+) cations and [BPh(4)](-) anions. In the cation, the non-H atoms of the butan-2-one group are approximately planar (r.m.s. deviation = 0.056 Å) and lie nearly perpendicular to the plane of the phenyl ring with a dihedral angle between...
